Danfoss PAH 70 High-Pressure Pump – Part Number 180B0042
The Danfoss PAH 70, part number 180B0042, is a compact axial piston pump built for demanding high-pressure water applications. What makes this pump stand out is its water-lubricated design, meaning no oil ever comes into contact with the moving parts. That simple detail removes the risk of oil contamination entirely, which matters a great deal in applications like humidification, flushing, and cleaning where purity counts. The pump is built from durable stainless steel, giving it a long service life even in tough working environments, and its low-pressure pulsation means it can typically run without a separate pulsation dampener.
Rated for a maximum flow of 31.1 GPM and outlet pressure up to 2320 psig, this pump has enough muscle for serious industrial and hydraulic work while still staying lightweight and easy to install. It can be mounted vertically or horizontally to fit tight equipment layouts, and it's flexible enough to run on either an electric motor or a combustion engine, so it adapts well to both stationary and mobile setups.
Beyond raw performance, the PAH 70 is genuinely easy to live with day to day. Its straightforward mechanical design keeps maintenance simple, and it's equally at home drawing from a boosted inlet supply or pulling water directly from a tank. Whether the task is fire suppression, dust control, industrial cleaning, or high-pressure hydraulic power, the 180B0042 delivers dependable output without unnecessary complexity.

Frequently Asked Questions
Q: Does the Danfoss PAH 70 pump require oil for lubrication?
No, the PAH 70 uses water itself to lubricate its moving internal parts, which eliminates the risk of oil contamination in the pumped fluid.
Q: Can the PAH 70 be mounted in any orientation?
Yes, its compact axial piston design allows it to be installed either vertically or horizontally, depending on the layout of your system.
Q: What power sources can drive the 180B0042 pump?
It can be powered by either an electric motor or a combustion engine, making it suitable for both stationary and mobile installations.
Q: Is a pulsation dampener needed with this pump?
Generally no, since the PAH 70 produces extremely low pressure pulsation on its own, though system-specific conditions should always be reviewed.
Q: What water supply conditions does the PAH 70 support?
It works well with either a boosted inlet pressure supply or by drawing water directly from a tank, giving flexibility in system design.
